in the mid-50's two youngish teenagers with new General licenses decided
to build a puzzle for the next radio club meeting. It consisted of two
of those Bud aluminum boxes. Box 1 had a cord to plug into the wall,
two switches, and two single wires coming from each end. It weighed
about 1/4 of a brick.
The two single wires went into the ends of Box 2 which had two #47 dial
lamps poking through rubber grommets on top. It weighed almost nothing.
Plugged in, Switch 1 turned Lamp 1 on and off, Switch 2 turned Lamp 2
on and off. We hacked 1/4 of a brick off and put it inside Box 2 with
duct tape.
You could have both lamps off, one or the other on, or both on, however
binary arithmetic had not yet arrived in Los Angeles and we failed to
sense the significance of that. Convinced we were going to stump
everyone at the meeting, we brought it out during the coffee break
before the raffle. None of our teen friends could figure it out. The
OT's remained silent but smiled a lot.
We finally said we'd give them a hint. "Box 1 contains a transformer,
two switches and two solid state diodes," just then coming onto the
market. "Box 2 contain two more diodes, two lamps, and 1/4 of a brick."
Still no one could draw the circuit, so Terry did for them. They
asked, "What's the 1/4 of a brick for?" Terry said, "To make it seem
substantial."
Rather than put a brick inside my P3, I put two little squares of
double-stick automobile moulding tape under the two front feet to keep
it planted on the shelf. While I'd like to think Elecraft has a whole
bunch of cool electronics and features to make use of all that empty
space about to be released, I suspect it is as long as it is so it would
keep the K-Line symmetric when lined up on the desk.

Lyle, KK7P, demoed a pre-production P3 to our DX club. When I picked it up I
told him Elecraft better put a steel plate inside if they wanted to get that
much money for so little weight.
